Abstract
This paper for the first time reports an all printed actively actuated thermochromic smart fabric device using a state of the art dispenser printing technique. The device consists of a UV curable thermochromic ink with an activation temperature of 33°C actuated by conductive track based printed heater. The device is printed on untreated polyester cotton fabric. It offers a significant improvement in flexibility and design freedom over the state of the art thermochromic fabric devices. The printed device changes colour from black to green in 10.8 s using 1.46 W DC power. It is shown that the time required for the device to change colour reduces tenfold with only a threefold increase in input power. It can be fabricated on other fabric or flexible substrates and in a range of colours and activation temperatures depending on the formulation chosen. The printed device is 30 x 21.5 mm which can be scaled up or down to suit the application. It can be used as an indicator in combination with sensors for smart fabric applications.
